There's definitely been breast augmentation surgery, just look at her pictures from a couple of months back... These things got H U G E! And since she doesnt show her nipples at all, i assume they did the "around the nipple" insection. Unless she shows them we can't be sure. Other that that, implants can now be inserted from just about anywhere into the body, be placed at the spot they want and just fill them with silicon gel afterwards. Through the armpits, through the belly button, whatever, as long as there are no visible scars.
I think it fits her to be honest...she is slowly turning into a petite bimbo. All i want is to see her get fucked at this point.
